The safe serializer is this one: https://github.com/irmen/serpent and it is a text based
protocol, so no, it is not affected by byte order. It uses Python literal expressions as
understood by ast.literal_eval().

Note that the endianness bug in my pickle implementation was fixed by the pull request
so it is no longer a known bug. But I still would like to be able to run the test suite
on both endianness platforms (or let someone else try it for me :-) )

Heh, yes; I used to have a PowerPC G4 mac mini (a big endian platform), but that machine
got replaced by an Intel based one (little endian, as all the other computers I have
access to). Ah well.
